Recruiting studies
- NCT07225621RecruitingPhase 2
Light and sound therapy for newly diagnosed glioblastoma
This trial tests a new approach that uses a light-sensitive drug and low-intensity ultrasound to make standard chemotherapy more effective for glioblastoma. If you have completed initial treatment with radiation and temozolomide without the tumor growing, you may be eligible.
Boston, MassachusettsAges 18–80 - NCT06047379RecruitingPhase 1/Phase 2
Testing NEO212 for brain tumors and metastases
This trial tests a new drug called NEO212 for people with certain brain tumors (like astrocytoma or glioblastoma) or cancer that has spread to the brain from other parts of the body. The goal is to see if it is safe and if it can help shrink or control the tumors.
Beverly Hills, CaliforniaAges 18 years+ - NCT03144167Recruiting
Blood and scan markers to predict benefit from bevacizumab
This study looks for blood test markers that may predict who survives at 6 months after starting bevacizumab for glioblastoma that has come back. It does not aim to cure the cancer by itself, but to improve doctors’ ability to choose the most helpful treatment plan.
Amiens, PicardieAges 18 years+ - NCT03383978RecruitingPhase 1
Test brain injections plus IV antibody for HER2-positive glioblastoma
This early-phase study tests a combination of cells injected directly into the brain and an IV antibody to treat recurrent HER2-positive glioblastoma (or a related tumor, gliosarcoma). It may help by attacking the tumor locally in the brain while the antibody boosts the immune system’s response.
Heidelberg, Baden-WurttembergAges 18 years+ - NCT03970447RecruitingPhase 2/Phase 3
Testing several treatment options for new or returning glioblastoma
This trial studies different treatment regimens for people with glioblastoma that is either newly diagnosed or has come back. It aims to find which treatment approach works best for controlling the tumor and improving outcomes.
Birmingham, AlabamaAges 18 years+ - NCT04188535Recruiting
MRI scans during radiation treatment
This study does repeated MRI (detailed brain/body imaging) while you receive radiation therapy. It aims to see how these serial scans relate to treatment and outcomes, which could help improve care planning for different cancers.
Boston, MassachusettsAges 18 years+ - NCT04266977Recruiting
Low-dose steroid timing for newly diagnosed brain tumor surgery
This trial looks at using dexamethasone (a steroid medicine) in a more restricted way for people newly diagnosed with likely glioblastoma who are planned for brain surgery. The goal is to see whether limiting steroid use can still control symptoms while reducing steroid exposure.
Sankt Gallen, St.GallenAges 18–90 - NCT04443010RecruitingPhase 1/Phase 2
Testing a new protein drug with standard treatment for new glioblastoma
This Phase 1/2 study tests whether adding a drug called L19TNF to standard chemoradiotherapy is safe and may work better than standard treatment alone for newly diagnosed glioblastoma. If you qualify, you would be closely monitored for side effects and treatment response.
ZurichAges 18 years+ - NCT04523688RecruitingPhase 2
Dendritic cell vaccine made from your own tumor cells
This Phase 2 study tests a personalized glioblastoma vaccine made from your own immune cells (collected by apheresis) and your own tumor material. It’s meant to help your immune system recognize and attack the cancer after standard chemotherapy and radiation.
Meldola, FCAges 18 years+ - NCT04559230RecruitingPhase 2
Treating recurrent glioblastoma with sacituzumab govitecan
This Phase 2 study tests sacituzumab govitecan in adults whose glioblastoma has come back after standard treatment (radiation plus temozolomide). It may help shrink the tumor in people whose tumor has a specific target (Trop-2).
Cleveland, OhioAges 18 years+ - NCT04573140RecruitingPhase 1
RNA vaccine study for newly diagnosed adult and pediatric brain tumors
This Phase 1 trial studies an “RNA-lipid particle” vaccine given after surgery for certain newly diagnosed brain cancers (glioblastoma in adults, high-grade glioma in children/teens). The goal is to see whether the vaccine is safe and can train the immune system to fight the tumor.
Washington D.C., District of ColumbiaAges 4 years+ - NCT04623931RecruitingPhase 2
Chemo and radiation for IDH-wildtype glioma
This Phase 2 study tests a combination of chemotherapy and radiation after surgery for certain brain tumors that are “IDH wildtype.” It aims to control the tumor and improve outcomes for people with specific types of glioma or glioblastoma.
Houston, TexasAges 18 years+ - NCT04708171Recruiting
Compare awake, asleep, or no mapping during brain tumor surgery
This study looks at whether surgeons get better safety and control during glioblastoma removal by using awake testing, asleep testing, or no mapping. Mapping helps identify brain areas involved in movement, speech, or vision to lower the risk of serious side effects.
San Francisco, CaliforniaAges 18–90 - NCT04752280Recruiting
Radiation for glioblastoma with photon or proton beams
This trial compares two ways of giving radiation—standard photon radiotherapy (IMRT) versus proton beam therapy—for people with glioblastoma. It may help find a safer or more effective radiation approach for shrinking tumors and improving outcomes.
HeidelbergAges 18 years+ - NCT04863950RecruitingPhase 2
Imipramine plus lomustine for recurrent glioblastoma
This study tests whether combining imipramine (a medicine used for mood and sometimes nerve pain) with lomustine (a chemotherapy) can slow or treat recurrent glioblastoma that has come back after standard radiation and temozolomide. It is mainly for adults who are well enough to travel through treatment and monitoring scans and blood tests.
San Antonio, TexasAges Any age - NCT04977375RecruitingPhase 1/Phase 2
Anti–PD-1 treatment plus focused radiation for recurrent glioblastoma
This trial tests a cancer-immunotherapy medicine (an anti–PD-1 antibody, similar to pembrolizumab) combined with precisely targeted radiation to treat glioblastoma that has come back or progressed. It may help your immune system recognize and attack the tumor while the radiation targets the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT05083754RecruitingPhase 1
New glioblastoma trial testing immune drug plus radiation
This Phase 1 study tests whether adding an immune therapy called retifanlimab to radiation (and a chemotherapy medicine called temozolomide, in some parts of the study) is safe and helpful for newly diagnosed glioblastoma patients after surgery with carmustine wafers. It aims to see how well this combination controls the cancer and what side effects are expected.
Baltimore, MarylandAges 18–100 - NCT05284643Recruiting
MRI-guided radiation and Avastin for recurrent brain glioblastoma
This trial tests whether using special MRI information to plan proton radiation, plus a drug called Avastin (bevacizumab), can help control recurrent glioblastoma (a fast-growing brain tumor) and improve outcomes. It mainly aims to treat tumor that has come back after prior standard radiation, using careful timing and imaging to target it safely.
Miami, FloridaAges 18 years+ - NCT05326334Recruiting
Study gut microbiome in new glioblastoma patients
This trial studies how changes in gut bacteria (gut microbiome) relate to outcomes in people with newly diagnosed glioblastoma receiving standard chemo-radiation. It may help doctors learn which gut-bacteria patterns go along with better or worse results during treatment.
Ottawa, OntarioAges 18 years+ - NCT05423210RecruitingEarly Phase 1
Atezolizumab with pre-surgery brain radiation for glioblastoma
This early-phase study tests atezolizumab (an immune therapy) together with radiation before brain surgery for glioblastoma. It aims to make the treatment safer and more effective before the tumor is removed.
Stony Brook, New YorkAges 18 years+ - NCT05432804RecruitingPhase 1/Phase 2
Selinexor added to temozolomide for recurring brain glioblastoma
This trial studies whether adding selinexor to the standard chemotherapy temozolomide (with radiation) can better treat glioblastoma that has come back after prior treatment. If you meet specific tumor, health, and lab requirements, the goal is to slow tumor growth or improve symptoms.
Phoenix, ArizonaAges 18 years+ - NCT05439278RecruitingPhase 3
Radiation schedules plus temozolomide for elderly glioblastoma
This study compares a standard radiation schedule versus a shorter, higher-dose radiation schedule, both with the chemotherapy medicine temozolomide, in older adults with newly diagnosed glioblastoma. It aims to see which approach works better and is practical for people age 70 and older.
SeoulAges 70 years+ - NCT05463848RecruitingPhase 2
Surgery plus pembrolizumab with olaparib and temozolomide for glioblastoma
This trial tests a combination treatment after surgery for people with glioblastoma that has come back once or twice. It aims to improve control of the tumor by adding immune therapy and targeted DNA-damage treatment along with chemotherapy.
Boston, MassachusettsAges 18 years+ - NCT05465954RecruitingPhase 2
Testing efinetakin and pembrolizumab for recurrent glioblastoma
